MiniSpec is a test/spec execution engine. It works out-of-the box with
TypeScript, ECMAScript (esm) and CommonJS (cjs) modules. It uses the
Why another test/spec execution engine?
The idea of MiniSpec cames from the need to write some unit-tests for a tiny library written in TypeScript. All testing framework were pretty big - with a lot of dependencies - and may not work well out-of-the-box with TypeScript.
Why does weight matter?
Less dependencies and a lightweight library means less resources consumed while downloading it and executing it. It also reduces the potential attack surface.
That means also fewer features. That is why MiniSpec purpose is to be used with small projects, which do not need advanced testing capabilities that may offer more popular alternatives.
